FINISHING 0]? BOOK COVERS.

Application filed November 4, 1927, Serial No. 231,115, and. in GreatBritain April 11, 1927.

This invention relates to a machine for laying metallic leaf on therounded backs of books, of miscellaneous sizes.

The object of the present invention is to provide a machine in which themetallic leaf can be quickly and economically laid, in one or morestrips on the rounded back of the book at a single operation.

According to this invention, the machine.

Fig. 3 is an elevation of one plate of the metallic leaf carrying devicelooking at the inside thereof.

Fig. 4 is an elevation of the other plate of. said device also showingthe inside thereof.

Fig. 5 is an edge View of the complete device for narrow metallic leaf.

Fig. 6 is a similar view to Fig. 5 for wide metallic leaf.

Figs. 7, 8 and 9 are an edge view, a side view and a sectional view online IX-IX respectively of a modified form of metallic'leaf carryingdevice for wide metallic leaf.

Figs. 10 and 11 are an edge view and a side view respectively of amodified form. of metallic leaf carrying device for narrow metallicleaf.

The machine comprises a rectangular base frame consisting of sidemembers 1, front member 2 and'back member 3. Extending between the sidemembers, perpendicular thereto, are the stationary holding means whichare constituted by the clamping members, one 4 of which is fixed and theother 5 of which is slidable towards or away from the one 4. Theclamping member 5 is slidably mounted on the frame by lugs 6 extendingover the upper and lower edges of the sides 1 and it. is movable by thequick pitched screw 7 operated 'by ahand wheel 8 at the front of theframe.

Pivotally mounted at 10 on the base frame is the rockable mounting meanscomprising the two upstanding side members 11, atransverse round bar 12to constitute ahandle, and a transverse framing bar 13. Slides 14 areprovided on the members 11, these slides carrying supporting members forthe metallic-leaf-carrying devices, which supporting members comprisetwo spacedtransverse members 15 16, one 15 having a longitudinallyextending slot 17. Thus the transverse members will take a requirednumber of said carrying devices and allow them to be fixed at therequired distance apart.

The metallic leaf carrying devices may be of two forms, one of which isshown in Figs. 36 and the other is shown in Figs. 7-11.

, In the form shown in Figs. 36, the device. comprises two spacedplates, one plate has a pair of lugs 21 fixed thereto, and these platesare adapted to fit between the frame members 1516 with the lugs 21 incontact with the inner, faces thereof. One of the lugs 21 is tapped at22 to receive a screw 23 which passes through the slot 17, thetightening or slackening of. which serves to fix the lug to thetransverse member or allow it to slide therein. Moreover, by removingthe screw the plates can be detached. Thus one plate 20 can be fixed tothe transverse frame members, hence this plate will hereinafter bereferred to as a fixed plate. The. other plate 24 has slots 25 inopposite side edges, corresponding with the position of the lugs 21 onthe plate 20, in which the lugs project, whereby the plate 24 isslidable on the lugs and can move towards the fixed plate. The platesare maintained in the required spaced relationship by means of sleeves27 and 28, located on pins29, said sleeves serving as distance pieces,and co-opcrating to this end with the screws 30 and nuts 31. The pins 29and thereby the sleeves-27 and 28 are not fixed directly to the platesbut are fixed to slides 32-33 of dovetail shape mounted to move incorrespondingly shaped slots 34, 35 respectively in the plates, underthe control of adjustment screws 36 rotatably fixed on the lugs 42 onthe slides and having a threaded engagement with the lugs 43 fixed onthe plates 2024. The slides are held in position by the plates 37. Areel of metallic leaf mounted on tissue is indicated by the chain dottedcircle 38,thisbei ng mounted on thesleeve 27. The end of the metallicleaf and tissue is secured to the periphery of a roller indicated by thechain dotted circle 39, which roller is mounted on the sleeve 28. A leafspring is provided fixed on the plate 20 and adapted to bear against theside of the reel so as to restrain movement of the latter, and a similarleaf spring 41 is fixed to the slide 32 and bears against the roller 39for a similar purpose.

With this form of carrier two sizes of carrier may be suthcient, onesuch as shown in Figs. 3-5 for narrow reels, and one, such as shown inFig. 6 (which is exactly the same as that described with reference toFigs. 35 except that the lugs 21 and screws 30 are longer) for largersizes. Intermediate sizes of reels within the capacity of the two sizesof carriers can be employed by using sleeves of ap propriate width.

In a form shown in Figs. 7-11 in which like references indicate likeparts to those described with reference to Figs. 35 with which theplates are very similar but in this case the carriers are made up tosuit certain standard widths of metallic leaf, and each carrier takesone standard size only. This may be more convenient in many casesbecause usually only two or three Widths of leaf may be required. Thearrangement differs from the prior arrangement, therefore, in that thefixed plate carries a transverse member 60 to which the movable plate 24is hinged at 61, and the movable plate is not slotted to engage the lugs25 but this plate is provided with holes 62 for the passage of screws 63fixed on the ends of said lugs, fastening members 64 being provided,slotted at 65 to engage with the head of the screw and thereby fix theplate to the lugs, the fastening members being pivotally mounted at 66so that they can be turned to disengage the screw when it is desired toopen the carrier. In this case also the screws 36 are each provided witha reduced shank portion 67 which passes through a hole 68 in the lugs 42and is provided with an abutment 69 at its end. This allows a bit ofplay between the screw 36 and the lug 42 which is taken up by theeoilspring 70 located around the screw and disposed between the two lugs42-43 Further a screw 71 is provided to adjust the tension of the spring40, which in this case is attached to the slide 33 instead of to theplate, and the spring also engages and is attached to the slide at apoint above the plates 37, a screw 72 being provided for adjusting thetension of the spring.

In order to allow for the necessary movement of the slide one of theplates 37 is slotted at 7 3 for passage of the screw 72.

Figs. 10 and 11 show a similar carrier for narrow leaf and in this case,it will be noticed that only a single adjusting screw 36 is provided,this being situated centrally of the carrier and engaging a yoke piece 75 connecting the two slides. In this case the slide on the movable plateis detachably attached to the yoke by the pin 7 4t fixed in the yoke andengaging in the hole 76 in the slide. The screw 36 engages with the yokein exactly the same manner that it engages with the lugs 42 and thespring 70 in this case is located between the member 60 and the yoke.

With the two forms of metallic leaf carrier the action is the same. Thearrangement is such that by rotating the roller 39 the tissue andmetallic leaf are together wound off the reel, with the metallic leaf onthe outer surface of the roller. The metallic leaf is removed in use, aswill be hereinafter explained, but the tissue is continuously wound onthe roller 39 untilthe reel is exhausted when it is removed from thesleeve 28 and a new reel is fitted. As the tissue is wound 011 theroller, it increases the effective diameter thereof and therebyincreases the extent to which the surface projects below the plates, andto compensate for this the adjusting screws 36 are provided, whereby theslide can be retracted periodically and the efiective surface of theroller maintained at about a constant distance from the plate. Moreover,these screws tend to allow for incli- Vidual adjustment of one rollerrelative to a roller in an adjacent carrier.

As previously stated, metallic leaf carriers, to the required number andat the required distance apart, are fixed between the transverse members1516. The book is placed between the clamping members and heldstationary thereby. The rod 12 is then grasped by the operator and movedforwardly. The rollers of the metallic leaf carriers with the metallicleaf upon their outer surfaces are thus moved into contact with one sideof the rounded back of the book, and, thereafter, continued movement ofthe rod 12 will causethe roller 39 to rotate due to contact with theback of the book, and this rolling will serve to draw the metallic leaffrom the reel and to lay it on the book. As the roller moves out of,contact with the back at the opposite or front side, the rotation of theroller will be stopped and owing to the flimsy nature of the metallicleaf further movement of the bar 12 will sever the leaf on the back ofthe book from the leaf on the roller. Springs are provided between theslides l t and the member 13 said springs serving as loading means andtending to press the slides and transverse members downwardly andthereby press the rollers firmly into contact with the back of the book.Stops 76, co-operating with projections 77 on the slides limit thedownward movement of the slides. Having reached the limit of theirforward stroke, the slides 14, together with all the parts mountedthereon, are raised by the operator placing his thumbs against the thumbpieces 79 on theupstanding extensions 80 and pressing these upwardlyagainst the action of the springs 75. The operator at the same timemoves the bar 12 and its associated parts backwards into their initialposition where they are supported by the rest 82. The book can then beremoved and subsequently treated at a subsequent and separate operationto the actual finishing operation in which the metallic leaf ispermanently impressed on the back of the book.

This is repeated at each operation, and at each operation there issimultaneously laid any suitable number of lines or strips of metallicleaf on the rounded back of the book.

It will be understood that by metallic leaf 1 mean, primarily, goldleaf, but any other metallic leaf can be used which will be similar togold leaf.
